Understanding CR2430 Battery

The lithium battery CR2430 3V is a small and light power source, which gives a steady 3V to your device. This lithium battery with the name “CR” (“C” refers to Lithium Manganese Dioxide chemistry, and “R” means round) is made to fit well in small gadgets. These CR 2430 batteries have lithium in them. This helps the batteries be better and last for longer time. You will need these 2430 batteries for things like smart watches, key fobs, and health monitors.

Frequently Asked About CR2430 LiMnO2 Button Cell Battery

How long will my order take, how can I pay, and what are the shipping options?

 

  • Lead Time:  Standard samples typically arrive in 7-12 days. Formal orders usually take around 25 days, though smaller quantities might ship faster, potentially within 15-18 days.
  • Payment Methods:  We accept various payment types, including T/T (Telegraphic Transfer), L/C (Letter of Credit), and PayPal.
  • Shipping:  We offer flexibility! Depending on your needs and location, we can ship your order via air freight (using carriers like FEDEX, DHL, UPS, EMS, etc.) or via sea freight.
  • Delivery Terms:  We can work with several common international shipping terms, including EXW, FCA, FOB, CFR, and DDU.

 

What is your minimum order quantity (MOQ), and can I get samples first?

We have a minimum order value of USD $500. The actual quantity you receive depends on the unit price of the specific batteries you choose. Absolutely! We understand you need to test our products. We're happy to provide samples for your evaluation before you place a formal order.

Can these coin cell batteries be customized for product integration?

Yes, we support the customization of CR cell batteries for product integration. This includes adding solder tabs and pins according to your specific requirements.

Is the CR2430 battery rechargeable?

No, the CR2430 is a primary (non-rechargeable) battery. It is designed for single use only, and attempting to recharge it is extremely dangerous. Recharging can lead to severe safety hazards, including internal short-circuits, leakage, overheating, rupture, or fire. Always replace a depleted CR2430 battery with a new one.

Are there any equivalent or replacement batteries for the CR2430?

Due to its unique combination of diameter (24mm) and thickness (3.0mm), there are no direct drop-in equivalents for the CR2430. Other batteries like the CR2450 have the same diameter but are much thicker (5.0mm), and the CR2032 has a smaller diameter. For the safety of your device, you should always replace a CR2430 with another CR2430 battery.

Can I use a CR2032 or CR2450 battery as a replacement for a CR2430?

No, you can not. This is a common point of confusion, but the CR2430, CR2032, and CR2450 are not interchangeable. While all are 3V lithium coin cells, they have different physical dimensions.

  • The CR2032 is both smaller in diameter (20mm) and slightly thicker (3.2mm).
  • The CR2450 is the same diameter (24mm) but significantly thicker (5.0mm). Using a different size battery can prevent proper contact, damage the device, or even cause a safety hazard. Always use the exact model specified by your device manufacturer.
What essential safety precautions should be followed when handling CR2430 batteries?

 

While generally safe when used correctly, proper handling is crucial. Because coin cell batteries can be a choking hazard, they must be kept out of reach of children and pets. Additionally, you should:

 

  • Never try to recharge the battery.
  • Do not short-circuit the terminals.
  • Avoid puncturing, crushing, or disassembling the cell.
  • Keep it away from open flames and extreme heat beyond its specified operating temperature.
  • Dispose of used or damaged batteries properly according to local regulations for lithium batteries.
